Rare B meson decays in the Minimal R-symmetric Supersymmetric Standard Model

TL;DR

This paper analyzes lepton flavor violating B meson decays within the minimal R-symmetric supersymmetric standard model, considering experimental constraints and predicting branching ratios influenced by model parameters.

Contribution

It provides new predictions for B meson decay branching ratios in the minimal R-symmetric SUSY model, accounting for experimental constraints on parameter space.

Findings

Branching ratio of B^0_d→μτ is four orders below future experimental sensitivity.

Decay B^0_d→μτ has potential for future observation.

Predictions are strongly affected by tanβ and off-diagonal mass matrix entries.

Abstract

Taking into account the constraints imposed by experimental data on the parameter space, we analyze the lepton flavor violating decays of B meson in the scenario of the minimal R-symmetric supersymmetric standard model. The prediction of the branching ratios is strongly affected by $\tan\beta$ and the off-diagonal entries in the slepton and squark mass matrices. The off-diagonal entries in the slepton mass matrix are constrained by the experimental limits of radiative two body decays of leptons. The off-diagonal entries in the squark mass matrix are constrained by the experimental limits of low energy observables related to B meson physics. The branching ratio of $B^0_d\rightarrow \mu \tau$ is predicted to be four orders of magnitude below the future experimental sensitivity and the decay $B^0_d\rightarrow \mu \tau$ has a higher chance of being observed in the future.
